Read the material named in the offer.
Ask whether the actual supplied roof is acrylic or polycarbonate and which named product is included. Resolve inconsistent descriptions before treating two proposals as equivalent.
Patio covers · Sedro-Woolley, Washington
Patio covers in Sedro-Woolley described as a clear plastic roof should identify whether the proposed material is acrylic or polycarbonate. Those material names should not be used interchangeably when comparing the offer with product information or calculator pricing.
Ask the supplier to name the material and exact roofing product in the written proposal. Keep that selection visible when a sample, brochure or initial price uses a different material description.

Choose offered dimensions and style for the calculator’s acrylic selection, then confirm the roof material and actual system with the provider.
Choose a callback time if you want help with a more detailed estimate, or send the request without one.
Patio cover construction
Separate the material identity from its transparency or panel shape. Two sheets can look similarly clear without being the same plastic; a description such as multiwall or corrugated also does not replace the material name.
Ask whether the actual supplied roof is acrylic or polycarbonate and which named product is included. Resolve inconsistent descriptions before treating two proposals as equivalent.
Have the supplier provide the selected roofing product’s own performance, care and installation information. A general comparison of plastics does not specify the complete roof system.
This calculator labels its main range as acrylic cover pricing. Ask for a separate proposal if the intended selection uses a different material or construction rather than transferring the range automatically.
Before work begins
Use the City Building Division resources to confirm the requirements for the roof, supports and associated work. Keep the actual selected roofing product consistent with the project information submitted for review.
Material identity and panel construction are separate details. Have the responsible provider identify both; this guide does not choose support spacing or authorize a sheet substitution.
Ask the supplier to identify whether the actual product is acrylic or polycarbonate rather than judging from transparency.
Have the proposal name both the material and panel construction.
Request pricing for the actual selected system instead of transferring the calculator’s named material range.
